A client's DNN logs are occupying 5.5GB disk space and growing at 140MB a day. Every entry in the latest log is the same thing with slightly different "Unique Key" entries. There's around 174,000 being logged per day!
This seems to be the problem but I don't know where to begin to look:
The property 'ModifiedTimeUtc' in object 'searchDocument' is invalid.
Here are 3 recent entries:
